The Microchip high performance 150 mA low dropout regulator offers high power supply rejection (PSRR) in an ultra-small 1 mm x 1 mm package for stringent space requirements and demanding performance. It operates from an input voltage from 2.5 V to 6.0 V and is capable of providing the output voltages of 1.0 V to 3.6 V making it ideal for USB port or 6 V AC adapter applications. It offers 2% initial accuracy, low dropout voltage 155 mV @ 150 mA, and low ground current typically 29 μA. It can also be put into a zero off-mode current state, drawing virtually no current when disabled.
